Let me tell you the story of an insect. Or of any and all insects in general.

An insect was born. The insect was very small; it trailed its parents and roamed around here and there, learning to fly and preparing to do insect work. Once it grew large enough, the insect went out to work, drinking blood from humans, sitting on food and doing all the work that insects do. It helped produce another insect, who it helped to fly and took care of. And then, as it got old, it became slow and unsteady, and was swatted out of existence.

You might feel superior to their simple existence, that our human lives have much more than a simple insect's life. Yet, I ask you, are our lives really different from those insects? From the point we begin to exist, we too train ourselves to work, through school or otherwise, then we work till our old age and give rise to the same cycle for another insect. 

And thus, I made the mistake of asking  the purpose of this endless cycle.

And thus, my hatred for all things was born.

When there is absolutely no purpose in doing whatever we do, isn't it natural for anyone to hate whatever they are doing? Imagine if you were forced to do numerical maths equations (like 20+20=40) for hours and hours everyday, without any payment, without any requirement for you to build maths skills and for no purpose. Won't you grow to hate those sessions, and try to avoid the fruitless waste of time? 

But if life itself seems to have no purpose (and hence a fruitless waste of time), how can one avoid it?

How am I so certain that life has no purpose? Because of two reasons. Firstly, most people refer to "making" a purpose of life for themselves, a certain goal or stature they want to achieve or work towards achieving forever. From that it follows that life inherently had/has no purpose anyway, and all other attempts to "make" a purpose are just feeble attempts to get people to work and not wander listless if they are above the ground. For whatever purpose you "make", it is just a way of staying motivated to live/work on, to delude oneself to survive, and may not, or I daresay, cannot be the actual purpose of existence.

Another reason is that whatever the purpose of your life be, the outcome of it will be the same:death. If the outcome is always the same, then how does the course your life takes matter anyway? Whether its a millionaire or someone with an income in hundreds and tens, both will face death eventually, and be obliterated from existence. Thus, one's existence becomes meaningless, for whatever route you take, the destination is the same.

Now, some people may believe in the idea of heaven/hell and the afterlife, and even in reincarnation. Yet, still, they too don't define the purpose of life. The theory of afterlife roughly says that the purpose of life is to be good, so that you enter heaven (or get reincarnated in a better life). This argument is flawed as well. Firstly, why would people be born, when they could directly live in heaven? Secondly, what is the purpose of existence in heaven anyway? To enjoy, or to put it plainly, just exist? Lastly, the theory doesn't justify the purpose of this life. While it predicts the consequences to be experienced in the next life, it doesn't account for what this life being lived for. Simply put, one is living in order to live a better life in the next life (or afterlife), which doesn't justify what they are living for in this life! 

Furthermore, there seems to be no purpose in the endless cycle of rebirth as well. If the aim of life is to get a better life in next life or afterlife, then what is the aim of the next life? What is the purpose of the endless cycle of better/worse lives? Rebirth also refers to moksh, which says that after a certain number of lives we get freedom from the cycle of rebirth. Then why did we enter the cycle in the first place, when the goal is to be free from it?!

No, despite being in the 21st century, there is still not an inkling of the elusive purpose of life, except that perhaps there isn't any purpose. In that case, we should all party till the end of days, to enjoy and distract ourselves from this crazy world. But instead, we all pursue false, artificial goals of working in society (or helping it) and being successful or reaching the top, as if that is the true purpose of life. If the purpose of life is to live, then we should be allowed to live as we please, without the constraints of the "realistic" world. And I do that too. In my dreams.
